Abstract: PURPOSE:To enable to move filing cards to the right feeding position at all times in an elevating type paper feeder by controlling the rise of an elevator in accordance with the output of each position sensor detecting a standard position and a limit position respectively. CONSTITUTION:When a feed command (a) is transmitted, a check pulse (b) is outputted from a delay circuit 31 with a fixed time lag, and a check signal (i) is outputted from an AND-circuit 32 by a detecting signal C of an H level emitted when a filing card detector 7 does not detect filing cards together with the feed command (a).

Title: Sputter source having rapid replaceable target and adaptor ring
Inventor: KENESU BII FUIIRUDAA
IPC: C23C14/34
Filed: 1989-02-10
Abstract: PURPOSE: To provide a sputtering source constituted to alloy the rapid and easy exchange of the sputtering target in the sputtering source, by providing the sputtering source with a spring means for holding the sputtering target at a prescribed position in order to attain good physical contact with an ambient cooling wall.  
     CONSTITUTION: The sputtering source, in which the sputtering target 110 and an adapter ring 40 constitutes a rapid exchange type target structure is composed in the following manner. The projecting part 46 of a spring 44 is rigidly press-bonded to the V-groove 118 in an inner rim 116 of the target 110 when the target 10 exists at prescribed position in the sputtering source. The engaging force by the spring 44 is the force sufficient for surely holding the target 110 in the prescribed position. If, however, the sufficient axial force is applied on the target 110, the target 110 is able to move in the axial direction of the target 110 by overcoming the additive force by the spring 44. Then, the extremely rapid removal and exchange of the target 110 are made possible by applying the axial force thereon.

Title: Differential input circuit
Inventor: KITANO JUNJIRO
IPC: H03F3/45
Filed: 1986-02-19
Abstract: PURPOSE:To obtain a differential input circuit constituting an operational amplifier of high oscillation stability by shunting a part of the collector current of the transistor TR of a differential input stage to a fixed voltage source. CONSTITUTION:When a differential input voltage (Vid=ViN+-ViN-) is generated in the input, a collector current difference DELTAIc (=Ic1-Ic2) between TRs Q3 and Q4 is generated by the TR operation in accordance with a formula 1. In this case, I3=I4 is true and a collector shunt ratio of TRs Q3 and Q4 is set to one. Consequently, Ic1=Ic2=2I3 is true. Since this current output is shunt by TRs Q3 and Q4 and a current IOUT=DELTAIc/2 flows to the output as the result, a conversion conductance gm of the differential input circuit is given in accordance with a formula 2. This conversion conductance is reduced to a half of that of a conventional differential input circuit, and the conversion conductance gm can be reduced without reducing the bias current of the differential input stage.

Title: Single-screw mixer
Inventor: KOSEKI NOBUO
IPC: B01F7/16
Filed: 1989-02-13
Abstract: PURPOSE:To efficiently perform homogenization by fixing an arm material to a vertical stirring means in the longitudinal direction thereof to mount one or more set of screw-like ribbons along the inner wall of a mixing container and providing a plurality of notch parts to said ribbons. CONSTITUTION:When a screw-shaped ribbon 2b is rotated, the material to be mixed on the surface of the ribbon 2b having an inclination 6 receives the action of the moving force being the resultant force of a centrifugal force component 5a and the pulling-down force component 5b of the inclined surface of said ribbon 2b. This moving force overcomes the adhesion force of the surface of the ribbon 2b and the material to be mixed and, therefore, even when a material to be mixed having viscosity is mixed, said material receives shearing action under sufficient moving force without generating adhesion on the surface of the ribbon 2b and is successively transferred to a void state from a compact state to move upwardly under screw action. By this method, the material can be uniformly mixed and dispersed.

Filed: 1982-03-02
Abstract: PURPOSE:To prevent the boring through a light emission pictures element, by applying polyvinyl alcohol acqueous solution on a substrate to be formed of the light emission picture element. CONSTITUTION:Prior to forming each light emission picture element, polyvinyl alcohol acqueous solution of 0.001-0.02wt% is applied on a substrate. From the study on a 20 inch phosphor screen constructed of light emission picture element dots having 0.3mm. screen pitch, it is found that when it is manufactured through same method with a phosphor screen having 0.6mm. screen pitch as shown on the drawing, the missing of green light emission picture element is 40 on average in the conventional method. When polyvinyl alchol of 0.001-0.002wt% is applied previously, it is reduced to 5-10. While when the concentration exceeds over 0.02%, the polyvinyl alcohol film is not dried sufficiently to increase the missing. While when the concentration lowers below 0.001%, the control of the concentration will be difficult.

Abstract: PURPOSE:To obtain a contrast image in which differences in the distributions of two kinds of electric potentials are indicated by applying voltage of a frequency higher than that of an electron ray to a sample, and detecting a signal from the sample by means of a lockin amplifier before the image is displayed on a displayer. CONSTITUTION:An electron ray 2 is irradiated on a sample 5. The signal of a scanning-signal-generating circuit 8 is supplied to a deflecting coil 6 and the deflecting coil (D) of a cathode-ray tube 10. The one end (A) of the sample 5 is earthed and voltage of a given frequency higher than the horizontal frequency of the electron ray 2 is applied from an osdillator 11 to the other end (B) to produce secondary electrons. The thus produced electrons are detected with a detector 15 and supplied to the cathode (K) of the cathode-ray tube 10 through a rockin amplifier 17 in which the signal of the oscillator 11 is used as a reference signal. As a result, an image in which areas corresponding to differences in the electric potential distribution of the sample 5 are emphasized can be obtained by applying voltages with different electric potential distributions to the sample 5 through the controlling of controllers 13 and 14, thereby enabling intuitive grasping of the image of the sample 5 to be achieved.
